Vpn B ⏰

: Data is wrapped in a secure layer, making it unreadable to anyone outside the tunnel.

A Virtual Private Network (VPN) functions by creating an "overlay". This means it uses encryption and tunneling to extend a private network across public infrastructure like the Internet. When an organization manages multiple such networks—for instance, one for Company A and another for —they are frequently labeled sequentially or alphabetically for administrative clarity. Key Technical Characteristics of VPN B : Data is wrapped in a secure layer,

: Even if VPN A and VPN B travel over the same physical router, their traffic remains completely separate via Virtual Routing and Forwarding (VRF). To ensure that cannot access Company A’s data,

In a service provider scenario, a single router (the Provider Edge or PE) might serve multiple clients. To ensure that cannot access Company A’s data, the network uses specific protocols: a typically refers to a specific

In complex enterprise networking, a typically refers to a specific, isolated virtual private network segment within a larger multi-tenant architecture. Unlike personal VPNs used for simple web browsing, "VPN B" is a designation often used in Multi-Protocol Label Switching (MPLS) or software-defined environments to distinguish between different corporate networks or departments sharing the same physical infrastructure.
